Re: Mounting hole problem
That text seems to be about adding screws to the BOM. I suppose I just don't get the implications of what you wrote.

Yes, you did, and I am grateful for all help, but you wrote this:

Re: Mounting hole problem
I always use pads with cooper. The pads may be connected to a net or not.

Re: Mounting hole problem
But how do you add mounting holes to a schematic? It seems impossible to get to a Mounting hole library from the Schematic screen. Do they have to be added as pads, adjusted to have no copper?

Unfortunately, the REF** is only a symptom of the real problem.

Re: Mounting hole problem
As you say, screws should be on the BOM, and the way to do this is add them
to the schematic as mechanical parts, which have a footprint of a mounting
hole. The mounting hole then gets automatically

Re: Mounting hole problem
In a distant past, I used two separate masses/grounds, which is easy in Kicad. But it's been a long time since I used only one.

Re: Mounting hole problem
Don't forget that the case is connected back to the central safety earth
via a length of wire, which will have impedance.

Re: Mounting hole problem
I don't agree with that, and I am involved in safety standards. Even if signal ground jumps to a high voltage due to a fault, the metal case is connected to chassis ground, which (in Class 1

Just a warning to remember to take into account creepage distance when
you have chassis ground on board. In other words, the distance between

Re: Mounting hole problem
Thank you. Yes, I do need to ground two of the mounting holes. These things are simple when you know how, but not if you don't. There are several steps to get exactly right.
